To all whom, it may concern.-

Be it known that I, LE CLAIRE STARK, of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented a new and useful Improvement in Photographic Cameras, of which the following is a description, reference being had to the accompanying drawings,which are a part of this specification.

My invention has relation to improvements in photographic cameras, more especially of that class known as panoramic cameras, wherein an extended view may be photographed by a single operation.

The primary objects had in view are:

First. To provide a panoramic camera wherein a revoluble cylinder is employed, said cylinder being located just to the rear of the light-opening and thereby forming the focal plane, and wherein the sensitized film wherein the light from the lens during an exposure of a view strikes the sensitized film upon a segment of the periphery of a cylinder, that portion of the cylinder so exposed forming the focal plane, whereby compactness in arrangement is secured and the necessity for employing a great number of rolls is avoided.

Third. To provide a photographic camera wherein the cylinder which permits motion to be imparted to the sensitized film is directly propelled by a pinion on a shaft meshing with a gear on the top of the tripod, the cylinder, pinion, and gear being so related and proportioned as to carry progressively into the line of light from the lens during one complete revolution of the camera a length of film precisely equal to the circumference of a circle the radius of which is the equivalent focal length of the lens. By this arrangement the proper length of film is carried into the line of light from the lens and also simplicity is secured and directness and positiveness of action obtained, with no chance for slipping, as in the case of a belt or similar device.

Fourth. To provide a panoramic camera wherein the film which is against the cylinder is pressed into contact with said cylinder by suitable rolls carried by spring-bearings and adapted to revolve and pay out the film at the same speed the cylinder and camera are revolved, and also adapting the film at all times during exposure to be practically the same distance from the lens. By this arrangement the film is obliged to move at the same rate of speed the cylinder and camera are revolved, thereby keeping the film taut and obviating all dragging.

Fifth. To provide an improved construction of automatic shutter which is simple in arrangement and adapted to give full exposure to both ends of the view, the construc tion also permitting the end of the film to be carried acrossthe front of the cylinder without difficulty.

Sixth. To provide an improved marking de' vice for separating the different views.

Seventh. To provide an improved form of gearing for indicating the end of the view and preventing the transit of the camera.

Eighth. To provide suitable means for preventing the camera from revolving backward.

Ninth. To provide an improved form of revolving tripod top or support for enabling the camera to be easily revolved while composing the View and adjusting the camera without setting in operation the mechanism of the camera proper, and thus moving the film, said revolving tripod-top being adapted to be used in connection with means for fastening said tripod-top when the operation of composing is finished.

With the above primary and other inci dental objects in View the invention consists of the devices and parts or their equivalents, as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a side view with parts of the tripod in section. Fig. 2 is a plan view in horizontal section. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4. is a vertical section through the front of the camera boX or casing. Fig. 5 is a side elevation with the box or casingin section. Fig. 6 is a fragmentary view of the lower end of the cylinder and shutter, and Fig. 7 is a detail sectional view through the shutter mechanism.

Referring to the drawings, thenumeral 8 indicates the tripod-legs, which are of the usual and well-known form of construction and are connected at their upper converging ends by the top plate .1, said top plate being provided on its under side with a central depending tubular boss 10. The upper surface of this top plate is provided with a central annular raised portion 11, which is surrounded by a loose ring or annulus 12, said ring or annulus provided with a projecting finger or pointer 13. Resting on top of the raised surface 11 is a circular plate 13 the upper edge of said plate being in the form of a toothed wheel 15. Depending from the circular plate is a tubular post 16, which post extends through the tubular boss and projects below said boss for a desired distance. This lower projecting portion is threaded to'receive a nut 17, which nut is adapted to be turned against the lower end of the tubular boss, a washer being preferably interposed between the nut and the boss.

The camera box or casing is indicated by the numeral 18. This box or casing has depending from its under side, near its forward end, a cylindrical boss 19. The lower end of this boss is somewhat reduced in diameter, as indicated at 20, and this lower reduced portion rests on top of the toothed wheel 15.

The lower reduced portion has also depending therefrom a stem 21, which forms the pivot or axis for the camera box or easing. This pivot or axis extends through the tubular post 10, and its lower end is threaded to receive a nut 22, which nut prevents the camera box or casing from being separated from the tripod-top. Surrounding the reduced portion of the cylindrical boss 19 is a toothed wheel 23, said wheel being held out of direct contact with wheel 15 by means of a suitable spacingwasher. This whee 23 has projecting from its upper surface, near its periphery, a stud or pin 24c, the upper end of said pin being preferably beveled, as clearly shown in Fig. l. livoted to the wheel 15 is a paw 25, which pawl'is normally held in engagement with the toothed wheel 23 by means of a spring 26. Secured to the under side of the camera-box and extending downwardly therefrom is a bracket 27, in which is pivoted a catch 28, said catch being acted upon by the free end of a spring 29.

Arranged vertically within the box or casing and preferably near one corner thereof is a winding-roll 30. The shaft of this roll extends below the box or casing and has thereon a pinion 31, forming part of and actuated by an ordinary clock mechanism consisting of a train of gears 32 and awinding-spring Arranged vertically at or near the center of the camera-box is acylinderSt. The shaft 35 of this cylinder passes through the bottom of the box and extends downwardly fora desired distance; the extension carrying a pinion 36, which is in mesh with the toothed wheel 15.

Arranged in the side of the camera-box opposite the side in which the winding-roll 30 is located is a feed-roll 37, from which the sensitized film 38 is unwound. The shaft or axis of this roll has its bearings in pivoted arms 39 39, arranged at the top and bottom of the box. Springs 4:0 40 act against the arms and tend to press the roll firmly against the cylinder 34:. One end of each of these springs is secured to a pivoted plate 11, said plate being provided with a segmental slot 42, through which a set-serew 4.3 passes. 3y loosening this set-screw the plate may be turned so as to regulate the tension of the spring.

Bearing against an opposite point of the periphery of the cylinder Si is a friction-roll it. The shaft of this roll also has its bearings in pivoted arms 45, engaging opposite ends of said shaft, and these arms are also engaged by the free ends of springs l6, which springs serve to hold the friction-roll in lirm engagement with the periphery of the cylinder. One end of each of these springs is also secured to a pivoted plate i7, which plate is provided with a segmetal slot 4C8, through which a set-screw e9 passes. 13y loosening the set-screw the plate can be turned so as to regulate the tension of the spring.

The shaft 35 of cylinder 34: has mounted freely thereon, above and below the upper and lower ends of said cylinder, arms 50'. The outer ends of these arms project slightly beyond the surface of the cylinder and have secured thereto a segmental shutter 51. The lower arm 50 is formed with a short extension 52, which is engaged by a spring 53, the tension of said spring being adjustable by means of a set-screw 54. (See Fig. 7.) The tendency of this spring is to normally keep the shutterin a closed position. Securedto the shutter is a spring-strip 55, the lower end of said strip being provided with an inwardlyextending pin 56. Seated in a countersunk portion of the lower end of the shutter is a transverse bolt 57, said bolt being provided with elongated slots 58 58, through which screws 59 59 extend, and thereby permit only of a limited movement of the bolt. One end of the bolt is bifurcated, and through this bifurcated portion extends the pin 56, said pin being adapted to normally engage the teeth of an annular rack 60 at the lower end of cylinder 34.

The numeral 61 indicates a vertical shaft which extends through the bottom of the camera-box for a short distance above said bottom and is formed or provided at its up per end with a crank 62, which crank is provided at its extremity with an upwardly-projecting lug. The lower extremity of the shaft 61 is formed with a projecting pointer 63, and medially said shaft carries a projecting finger (A, which extends over the toothed wheel 23.

Immediately in front of the cylinder St is a chamber 65. The rear wall of this chamber is provided with a light-opening (JG. Immediately back of the rear wall of chamber (55 is a curved plate 67, said plate also having a li ght-openin g (38, which registers with the corresponding opening 66. This plate iscurved in the same are of a circle as the cylinder 34 and has one end flanged inwardly, as indicated at 69, to form a stop for the swinging of the shutter in one direction. It will be noticed particularly from Figs. 6 and 7 that the bolt 57 is provided at a medial point with a projecting stud 7 O, which is adapted to extend into a recess or slot 71 for its accommodation formed in the plate 67. Fig. 2 of the drawings shows the shutter closed and the pin 56 of the spring-strip 55 in engagement with the teeth of the annular rack 60. Now when the cylinder 34 is revolved in the direction of the arrow, Fig. 2, the engagement of the teeth of the rack 60 with this pin 56 will cause the shutter to be moved with the cylinder. After the shutterhas been thus moved a slight distance the stud 70 of the bolt will contact with one end of the recess or slot 71 of plate 67, and this will cause a movement of the bolt 57 in a reverse direction to that in which it was moved with the shutter, the movement in said reverse direction being limited by the screws 59 contacting with the ends of the elongated slots 58 in said bolt. It will be understood that the bifurcated end, hereinbefore referred to, of the bolt 57 has a beveled or raised surface forming a cam, as indicated at '72, and as the bolt thus moves in a reverse direction said cam-surface will act on the pin 56, and thereby throw said pin outwardly out of engagementwith the annular rack 60. (See Fig. 7.) It will also be ob served that one edge of the shutter is provided with a projection 73. This projection is adapted to pass by the end of a spring 74, so as to be engaged by said spring just before the pin 56 is brought out of engagement with the annular rack 60, so that the moment the disengagement occurs the shutter is prevented from being swung to a closed posit-ion by the action of the spring 53.

The front of the box or casing has projectin g therefrom an extension forming the usual light-funnel 75. Extending from the front of this funnel is the lens-tube 76. The vertical height of this tube is preferably made adj ustable, and for this purpose it is secured to and projects from a plate 77. This plate has its opposite edges flanged around the sides of the funnel for a short distance, and one of these flanges is provided with an inwardlyprojecting lip 78, which fits in a correspondingguidc-groove 79 of the funnel. The other side flange of the plate is provided with a longitudinal slot 80, through which a, setscrew 81 passes and enters the funnel. By loosening this set-screw it is obvious that the lens-tube may be raised or lowered to suit requiremcnts.

\Vithin' the chamber is a pivoted composer or view-finder consisting of a mirror 82, said mirror being secured at its upper and lower ends to arms 83 S3. The upper arm has extending upwardly therefrom through the top of the box or casing a shaft 84, the

proper place for cutting the film.

upper extremity of said shaft having connected thereto an operating handleor crank 85. The mirror is normally turned to the full-line position shown in Fig. 2. WVhen it is desired to compose or find the view, the mirror is turned to the dotted-line position shown in Fig. 2 simply by manipulating the handle 85, said handle being made to engage a catch 86 in order to hold the mirror to this adjusted position. In the side wall of the chamber 65 is provided an opening, which is closed by a focusing-screen 87, composed of ground glass or other suitable material. The side of thecam-era box or casing is also provided with an opening 88, which is in register with the glass-covered opening of the chamber 65, said opening 88 being normally closed bymeans of a door 39. When the mirror is turned to the clotted-line position shown in Fig. 2, it will be seen that it is at so that when the door 89 is opened the object will be plainly discernible through the ground glass 87. After the view is properly composed the mirror of course is turned back to the full-line position shown.

I also prefer to provide my improved camera with a safety-shutter 90, which is located just in front of the opening 66. This shutter fits in suitable guide-grooves and is adapted to be operated by means of a rod 91, projecting through the side of the box or casing. This shutter is advisably pushed to a closed position during the initial adjustment of the camera preparatory to taking a photograph in order to effectually prevent the light from passing through the opening 66 onto the sensitized film should the shutter 51 by any means become accidentally opened.

I also employ in connection with my improvements marking mechanism, whereby a mark is drawn across the sensitized film, so as to separate the different views on the film and thereby act as a guide to determine the To this end I provide a suitable rail consisting of a rod 92. This rod is connected at its upper end to an angle-iron 9.3, and itslower end passes through another angle-iron 9i. Adapted to travel on the rail is a carriage 95, said carriage having extending therefrom an operating-rod 96, which rod projects through the top of the box or casing. 93 and 94E not only serve as bearings for the rail 92, but also limit the up-an'd-down movemen ts, respectively, of the carriage. Pivoted to the carriage is a plate 97, said plate being provided with a segmental slot 93. Through this segmental slot passes a screw 99 and enters the carriage. Tonnected to an extension from the plate 97 is a spring 100, said spring carrying at its end a pencil 101. The upper end of the spring is slanted toward the cylinder 34-, and when the carriage is at the lowest point of itstra'vel the pencil is held out of The angle-irons engagement with the sensitized film on the cylinder 31 by the engagement of a bracket or projection 102 with the slanting portion of the spring. On the up movement of the carriage, however, the slanting portion of the spring is pulled above the bracket 102, and this permits the spring to spring toward the cylinder 81, and consequently bring the pencil into contact with the surface of the sensitized film, thereby making a mark across the greater portion of the width of said film. On the down movement of the carriage a mark is likewise made on the film until the slanting portion of the spring is acted upon by the bracket 102, when of course the pencil is drawn out of contact with the paper. The sides of the box or casing are also advisably provided with doors 103 103 for convenience in obtaining access to the interior rolls. It will be understood, however, that the particular form and construction of the box or casing herein shown and described are not absolutely essential, as any other desired form may be substituted in lieu thereof.

An explanation of the operation of my invention will now be given. In the first place care should be taken that the safety-shutter 90 is closed. The nut 17 is now loosened. This will permit of the swinging around together of the top plate 11 and its integral wheel 15, as well as the wheel 23 and the camera box or casing, by reason of the fact that the top plate is held to the wheel 23 by the pawl 25 and the wheel 23 to the camera box or casing by the engagement of the catch 28 with the stud or pin 21. Before this is done, however, the door 89 is opened and the mirror adjusted to the dotted-line position shown in Fig. The parts are swung around, as just explained, until the camera is pointed toward the object at the extreme left of the view desired to be photographed and which is delineated on the ground glass. As soon as this is brought to view the rotation of the parts referred to is stopped and the ring 12 is turned so as to bring the pointer 13 into register with the pointer 63. This pointer 63 therefore determines the terminal point of the view. The camera-box, the wheel 23, and plate 11 are next swung around together in the opposite direction until the camerapoints toward the object at the extreme right of the view desired to be photographed and which is delineated on the ground glass. The next step is to tighten the nut 17, so as to prevent the plate 11 from rotating, and then release the pawl 25 and catch 28 and turn wheel 23 around until the stud or pin 21 is in register with the pointer 13, and the pawl 25 is then again permitted to engage the teeth of the wheel 23, so as to hold said wheel to its adjusted position. The mirror 82 is now swung around to the full-line position shown in Fig. 2 and the safety-shutter 90 is opened. The camera is now in position for being swung around from the initial point of view for the purpose of taking the photograph. The camera being revolved 011 its pivot and the wheel 15 being held stationary and being in mesh with the pinion 36, said pinion 36 will be revolved, and hence cause a revolving of the cylinder 31. The revolution of this cylinder will cause the sensitized film to unwind from the roll 37 and wind up 011 the roll 30 by reason of being pressed into contact with cylinder 31 by friction-roll 11. The surface of the cylinder is preferably roughened, so as to take firm hold of the film and prevent slipping of the same. The roll 11 is also advisably covered with felt or similar material, and the cylinder 31 and roll 11 are somewhat longer than the width of the film,so that the felt comes directly in contact with the roughened surface of the cylinder above and below the edges of the film. At the commencement of the revolution of the cylinder the annular rack at the lower end of said cylinder will act on the pin 56 and cause a quick opening of the shutter 51 in the manner hereinbet'ore fully pointed out, the shutter being held in its open position by means of the spring 71. After the camera has been revolved a certain distance the finger 61 will contact with the pin 21 and cause a turning of the shaft (31, which shaft will turn the crank 62, and thus throw the spring 71 out of engagement with the projection 7 3 of the shutter. The moment the shutter is thus released the spring 53, acting on the arm 50, will cause a swinging of said arm and a consequent turning of the shutter 51 to a closed position. The turning of the shutter carries with it the bolt 57, said bolt moving until the stud thereof comes into contact with the edge of the recess or slot 71 of the plate 67, when of course further movementof said bolt isprevented. The shutter, however, completes its movement and causes the release of the pin 56 from the camsurface 72 of the bolt, thereby permitting said pin 56 to spring into engagement with the teeth of the annular rack 00 ready for another turning of the cylinder 31. After the finger 61 engages the pin 21 it will be understood that the bracket 27 comes into contact with said pin21, and thereby prevents further rotation of the camera box or casing in that direction, and immediately following this contact the catch 28 rides over the beveled edge of the stud 21, and thereby prevents rotation of the camera in the reverse direction, so that the camera box or casing is held against rotation in any direction.

\Vhile I have herein shown and described many details of construction, yet I do not wish to be understood as confining myself thereto, inasmuch as it will be obvious that many of these details may be changed or varied without departing from the broad scope and spirit of my invention.
